40 Amp Auto-Cutoff ModuleThe ACM's small size and low weight allows you to take it wherever you need to discharge your battery packs. No need for AC power or another battery to worry about, the ACM runs itself from the 6V-24V battery pack being discharged.

The
CamLight Systems Auto-Cutoff Module is connected between a NiCd or
NiMH battery pack and the load used to discharge it. The ACM accurately
monitors your pack's voltage level as it discharges and disconnects
the load when the battery pack has reached the selected cutoff voltage.
Using just the ACM and your favorite load, you can safely discharge
any of 8 different voltage NiCd or NiMH packs, from the tinest cells
to the largest.

The
Auto-Cutoff Module (ACM) can be used to:• Safely condition your NiCd battery packs by making it easy to discharge
to a known voltage every time.
• Test the capacity of your NiCd or NiMH battery packs by using the ACM
along with a watt-hour meter like the Astroflight Whattmeter.
• Safely test new battery packs, motors or drive train setups at high discharge
current rates.
• Quickly discharge your battery packs down to 0.9V/cell before placing
them in a discharge tray (to discharge each cell individually).

Also
includes the following features:• Any of the eight cutoff voltages are selectable via a DIP switch.
• Can be used with an external load or on their own to discharge a battery
pack slowly.
• Solid-state output, no relay contacts to arc or stick together.
• The ACM-40F's integral fan cools your battery pack or load while discharging.
Note: The fan starts slowing down at voltages below 12V and will provide less
cooling air at these lower battery pack voltages. With 6V packs, the fan is only
slowly pushing the air.
• After pressing the Start button, a green LED indicates that the pack is
discharging. If the LED lights up red when you connect the battery pack, the
leads need to be reversed.
• Protected from short-circuits, reversed polarity, over-temperature, over-current,
and surge current conditions.
• All switch settings and connections are clearly marked.

The ACM's small
size and low weight allows you to take it wherever you need to discharge
your battery packs. No need for AC power or another battery to worry
